Generally, house spiders are brownish or grayish in color. They are approximately 1/8” to 3/8” in body length. Female house spiders have round abdomens while males have elongated abdomens. 

When bothered, some spiders will bite, but they usually cannot penetrate the skin of humans. Brown recluse and black widow spiders, which are poisonous, are not native to our area. Indoors, they are more of a nuisance because of their tendency to build nasty webs.
